Description

Technical Field

[0001] This application relates to the technical field of natural gas pipeline construction, and in particular to a clamping device for natural gas pipeline construction. Background Technology

[0002] In the docking operation of natural gas pipelines, different pipe sections are welded together. The clamping equipment can firmly fix the pipes to be docked in a suitable position and angle, so that the axial, radial and angular dimensions can be accurately positioned, which facilitates the construction personnel to carry out subsequent processes such as welding.

[0003] A search revealed Chinese Patent Publication No. CN221075509U, which discloses a clamping device for natural gas pipeline construction. By configuring a rotating ring, a push rod, and a clamping plate, the rotating ring can drive the slide groove to rotate, allowing the slider to slide inside the slide groove. The slider then drives the clamping plate to move via the push rod. This allows for the rapid clamping and fixing of pipelines of different sizes, making the operation simple and improving the practicality of the device.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing technologies generally only allow for single-position clamping and fixing of pipelines, which can easily lead to situations such as pipeline rotation around the clamping point or sliding in the axial or radial direction, resulting in instability and making it difficult to guarantee installation accuracy when connecting and installing long-distance natural gas pipelines. Utility Model Content

[0005] In order to improve the stability of clamping and fixing and ensure installation accuracy, this application provides a clamping device for natural gas pipeline construction.

[0007] Optionally, the clamping assembly includes a bidirectional threaded rod, which is rotatably mounted on the mounting plate. Clamping plates are provided at both ends of the bidirectional threaded rod, and the clamping plates are slidably disposed with respect to the mounting plate. The clamping plates are threadedly connected to the bidirectional threaded rod.

[0008] Optionally, the transmission assembly includes a drive rod rotatably mounted on the base, and a sleeve slidably disposed on the drive rod, the sleeve being rotatably mounted on the adjustment plate.

[0009] Optionally, a rotating shaft is provided between the sleeve and the bidirectional threaded rod. The rotating shaft is rotatably mounted on the adjusting plate. A bevel gear is installed on both the upper end of the rotating shaft and the bidirectional threaded rod. The two bevel gears mesh and drive each other. A bevel gear is installed on the lower end of the rotating shaft and the sleeve. The two bevel gears mesh and drive each other.

[0010] Optionally, the mounting plate is rotatably connected to the adjusting plate, a fixing bolt is provided between the adjusting plate and the mounting plate, the adjusting plate is provided with a threaded hole, and the fixing bolt passes through the mounting plate and is threadedly connected to the threaded hole.

[0011] Optionally, a worm gear is installed in the middle of the drive rod, and a worm is engaged on one side of the worm gear. The worm is rotatably mounted on the base, and a protective shell is provided on the outer side of the worm gear and the worm.

[0012] Optionally, the fixing component includes a fixing bolt and a fixing hole. The fixing hole is disposed on the base. One end of the fixing bolt passes through the adjusting plate and is threadedly connected to the fixing hole. A limit plate is disposed on one side of the adjusting plate, and the limit plate is mounted on the base.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model includes components such as an adjusting plate, a mounting plate, a base, bidirectional threaded rods, and a clamping plate. During operation, the position of the adjusting plate is restricted by a fixing component, thereby installing the adjusting plate at a designated position on the base. The two bidirectional threaded rods are driven to rotate by a transmission component, and the bidirectional threaded rods drive the clamping plate to slide on the mounting plate, thereby achieving clamping and fixing of the pipeline at different positions, avoiding unstable clamping and improving installation accuracy.

[0015] 2. This utility model, by providing components such as fixing bolts, threaded holes, and mounting plates, allows the fixing bolts to be removed from the threaded holes during operation through the cooperation between the fixing bolt components and the threaded holes, thereby releasing the restriction on the mounting plate. Subsequently, the mounting plate is rotated, causing the clamping components to rotate as well. After rotating to the preset position, it is fixed again by the fixing bolts, so that both clamping components can fix different pipes and maintain the relative position of the two pipes, thus improving the applicability of the device.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] This application discloses a clamping device for natural gas pipeline construction. For example... Figure 1 , Figure 3 As shown, it includes a base 1, an adjustment plate 2 is provided on the base 1, multiple adjustment plates 2 are provided, an installation plate 6 is provided on the adjustment plate 2, the installation plate 6 is rotatably connected to the adjustment plate 2, a fixing bolt 7 is provided between the adjustment plate 2 and the installation plate 6, and multiple threaded holes 8 are provided on the adjustment plate 2, with the multiple threaded holes 8 evenly distributed around the circumference.

[0023] See Figure 1 , Figure 4 As shown, the fixing bolt 7 passes through the mounting plate 6 and is threadedly connected to the threaded hole 8. The mounting plate 6 is provided with a clamping assembly, which includes a bidirectional threaded rod 10. The bidirectional threaded rod 10 is rotatably mounted on the mounting plate 6. Clamping plates 9 are provided at both ends of the bidirectional threaded rod 10. The side of the two clamping plates 9 that is close to each other is set with an arc. The clamping plates 9 are slidably set with the mounting plate 6. The clamping plates 9 are threadedly connected to the bidirectional threaded rod 10.

[0024] See Figure 1 , Figure 2 As shown, a fixing assembly is provided between the adjusting plate 2 and the base 1. The fixing assembly includes a fixing bolt 3 and a fixing hole 4. The fixing hole 4 is provided on the base 1, and multiple fixing holes 4 are provided and evenly distributed. One end of the fixing bolt 3 passes through the adjusting plate 2 and is threadedly connected to the fixing hole 4. A limit plate 5 is provided on one side of the adjusting plate 2 and is installed on the base 1. A transmission assembly is provided between the two mounting plates 6. The transmission assembly includes a drive rod 13 and is rotatably installed on the base 1.

[0025] See Figure 2 , Figure 3As shown, a worm gear 17 is installed in the middle of the drive rod 13, and a worm 16 is meshed on one side of the worm gear 17. The worm 16 is rotatably mounted on the base 1. A protective shell 18 is provided on the outer side of the worm gear 17 and the worm 16. A sleeve 14 is slidably mounted on the drive rod 13. The sleeve 14 is rotatably mounted on the adjusting plate 2. The meshing between the worm 16 and the worm gear 17 realizes the self-locking of the drive rod 13, preventing the drive rod 13 from automatically rotating in the opposite direction.

[0026] See Figure 2 , Figure 3 , Figure 4 As shown, a rotating shaft 11 is provided between the sleeve 14 and the double-threaded rod 10. The rotating shaft 11 is rotatably mounted on the adjusting plate 2. Both the upper end of the rotating shaft 11 and the double-threaded rod 10 are equipped with bevel gear 12, which mesh and drive each other. The lower end of the rotating shaft 11 and the sleeve 14 are equipped with bevel gear 15, which mesh and drive each other.

[0027] The implementation principle of a clamping device for natural gas pipeline construction according to an embodiment of this application is as follows: Before use, the angle of the clamping assembly is first adjusted. The operator drives the fixing bolt 7 to rotate, causing one end of the fixing bolt 7 to move out of the threaded hole 8. Then, the mounting plate 6 is driven to rotate, and the mounting plate 6 drives the clamping assembly to rotate accordingly, adjusting the clamping assembly to a preset angle. Next, the fixing bolt 7 is driven to rotate in the opposite direction and connect with the corresponding threaded hole 8, thereby fixing the position of the mounting plate 6. Then, the distance between the two adjusting plates 2 is adjusted according to the actual situation, and the fixing bolt 3 is driven to rotate, causing the fixing bolt 3 to separate from the fixing hole 4, thereby releasing the restriction on the adjusting plate 2. Then, the driving adjustment plate 2 moves. After adjusting the adjustment plate 2 to the preset position, the reverse driving fixing bolt 3 rotates and connects with the corresponding fixing hole 4. Then, the base 1 is fixed in the designated position, so that the pipe is in the middle of the clamping plate 9. Then, the operator drives the worm gear 16 to rotate. The worm gear 16 drives the driving rod 13 to rotate through the engagement with the worm wheel 17. The driving rod 13 drives the sleeve 14 to rotate. The sleeve 14 drives the rotating shaft 11 to rotate through the meshing between the bevel gears 12. The rotating shaft 11 drives the bidirectional threaded rod 10 to rotate through the meshing between the bevel gears 12. The bidirectional threaded rod 10 drives the two clamping plates 9 to move closer to each other, thereby achieving clamping and fixing of the pipe.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
